The FAQ section on the GAPS website has been greatly expanded. Lots of good information there.
Life is a Palindrome has notes from a series of talks from Dr. NCM. Even more info.
Also - know someone with heart problems? Put Your Heart in Your Mouth is the book for them. Dr. NCM is also coming out with another GAPS book - Gut and Physiology. The original GAPS book has also been updated and expanded.
I wish you continued healing through diet!
